IMPROVEMENT? IN GANG-PLOUGEfi o'l e Srlgctult match it in that fighters Ethinliimt nailing; tint mi fl e. fitl'lllt,

TO ALL WHOM IT MAY CONCERN:

Be it known that we, JOSEPH INGHAM and JAMES INGHAM, of? San: .I'os, Santa Ola-12a county, State; at" California, have invented certain new and usefiil Impizovcments inr'G'nwtrg Ploughs; and we do heebyfdieclaltc the following description and accompanying drawings: are suilioicntxto; enableany person. skillledi the" fillEiIfllt'SClGIlCQ', to which it most nearly appcrtains to make; and use; our saifdl invention; or improvements;without furtheri'nvene tion or experiment.

The nature of our invention-is to provide: fltlh improved gang-plough, so constructed that, therpillorug hs can: be: regulated by the operator from his seat; and consists of gene o. wheels and segments for raisinga i the ploughs, and regulating their height by am adjfusti'ng screw;; also to a toothed connection of the lionelting; e, that,

although the furrow-wheel inay be the lowest, the; axle; will he horizontal; to a. device for shntthig; the

draught connection from right tolieiit'g thew'holeelbieir attached to: a suitable frame,- mounited on. whee In order to more fully illustrate ai escnibe our invention, reference is had to the accompanying drawings, and letters marked thereon, o.f?'w,hi'c,h-

Figure 1. 'A and A are parallel pieces cozurpos" ieframe, and are attached to the axle: Ct.v Thepiloughs; B and B are attached to the independent bars: G and 7",, which are connected-to the parallel parts of the: frame by loose bolts 0 and c. Segmental racks D and. D are attached to each end off'the-se: bars, working in toothed. wheels E and E by the pinions F and F, the pinion F being placed at the top of the wheel E, at the right hand of the drivers seat. Tirewhf is: attached to the axle G", and has a counterpart, E, between which and the wheel E the pinion F works; The wheels and pinii'ons are all raised above the frame, and operate in steps ol brackets attached to it. drivers seatili is placed above the forward toothed wheel, and beneath it is the foot-board H, having av lever, I, which fits between the cogs of the wheel E and prevents the wheels and pinions from working- Within easy reach of the driver is a crank, J, which turns the pinion F, which operates or actuates the wheels E" and E, raising or lowering the racks D and D"; thus regulating the depth of the ploughs. Near the left-hand clriving-wheel the axle Gr is divided, and has a. toothed ruck, K aad'K, strongly attached by bolts to each portion of it. This rack forms two upright pieces which are slotted, and in which a bolt and nut operate, holding them together By this toothed rack and construction the ploughs will all have a corresponding depth, which is accomplished by raising or lowering the left wheel, so that the axle will he horizontal, although the furrow-wheel is always the lowest; In order to regulate the draught, the pole is attached to the machine, by means of two eyes L and L, one of which slides loosely on the bar M, whiie the other moves on a screw, m, passing through it, hy means of which the pole may be moved from side to side and kept in place, thus changing position as the draught is greater on one side or the other. Set-screws a a supported by bands are placed under the bars G and O to prevent the points of the plonghs from running too deep. By means of our improved mechanism, the depth at which the ploughs enter the soil may be regulated with great accuracy, and each plough be made to turn an equally deep furrow. The draught is also rendered equal in whatever soil the ploughs may be used.

Having thus described our invention, what we claim, and desire to secure by Letters Patent, is-

1. The movable pivoted barsC O, with-the segments D D, wheels E E, and piuions F F, to raise and lower the ploughs, substantially as described.

2. The two-part axle Gr, with the vertical connecting acks Ii K, to make the ploughs cut to an equal depth, as described. p l 3. The eyes L L, together with the bar M, and screw m, for the purpose of regulating the draught, substantially as described. V i

In witness whereof we have hereunto set our hands and uflixed our seals.
